Description

-;,.,. .. .1 . Изобретение относитс  к области машиностроени  и предназначено дл  сЬединени  различных деталей, машин, например втулки и вала, вращающихс  с больщой скоростью. По основному авт. св. № 257931 известен конический штифт с проточкой со стороны основани  конуса и с центром т жести, смещённым в сторону вершины конуса за ось вращени  вала, 1фичем в нижней части проточки, наход щейс  за осью вращени  вала, установлена пробка из материала с больщим удельным весом, чем удельный вес материала щтифта Cl3. . Недост атком известной конструкции конического щтифта  вл етс  то, что пробка установлена неподвижно. Это 3atpyflн ет балансировку узла деталей (вала и втулки), соедин емых с помощью извес ного конического щтифта, работающих При высоких скорост х вращени . Цель изобретени  - обеспечение удо&ства эксплуатации. Поставленна  цель достигаетс  тем что предлагаемый щтифт снабжен пружиной, а пробка установлена с возможностью , осевого перемещени  и поджата пружиной. При .этом пр1обка может быть соединена со штифтом с помощью резьбового соединени . : v , На фиг. 1 изображен предлагаемый . . конический штифт, общий вид; на фиг. 2вид по стрелке А на фиг. 1. Конический штифт, выполненный в виде усеченного конуса 1, имеет со стороны большего основани  глухую йроточку 2, в которой нарёэайа резьба 3. В нижней части проточки,наход шейс  за осью вращени  вала, установлена пробка 4, взаимодействующа  с проточкой по резьбе . При этом пробка вь1полнена из материала с большим удельным весом, чем удельный эес мач-ернала штифта, например меди, обеспечива  смещение центра т жести щтифта в сторону верщины конуса , тем Самым предохран   его от случайного выпадание в процессе работы.-;,.,. .. .one . The invention relates to the field of mechanical engineering and is intended for the interconnection of various parts, machines, such as a sleeve and a shaft, rotating at high speed. According to the main author. St. No. 257931 is known for a tapered pin with a groove on the side of the base of the cone and with a center of gravity shifted towards the apex of the cone beyond the axis of rotation of the shaft, 1 with a lower part of the groove located behind the axis of rotation of the shaft, a plug with a material with a greater specific gravity than the proportion of cl3 material. . A disadvantage of the known conical schtift design is that the plug is fixedly mounted. This is a three-way balancing assembly of parts (shaft and sleeve), connected by means of a conventional conical pin, working at high speeds of rotation. The purpose of the invention is to ensure the comfort & The goal is achieved by the fact that the proposed pin is equipped with a spring, and the plug is installed with the possibility of axial movement and is preloaded by a spring. In this case, the board can be connected to the pin with the help of a threaded joint. : v, FIG. 1 depicts the proposed. . conical pin, general appearance; in fig. 2 view along arrow A in FIG. 1. A conical pin, made in the shape of a truncated cone 1, has a deaf yrotochka 2 on the side of the larger base, in which there is an open thread 3. In the lower part of the groove, located behind the axis of rotation of the shaft, a plug 4 is installed, which interacts with the groove on the thread. At the same time, the cork is made of a material with a higher specific weight than the specific power of the pin, for example, copper, providing a shift of the center of gravity of the pin to the side of the cone, thereby protecting it from accidental falling out during operation.
